Why this guide exists
Panama has become an accessible corridor for US companies hiring in the Americas. Panama City has a growing pool of software, support, and finance talent, the country sits in the US Eastern and Central time band, and many Panamanian professionals already work with international clients in English. For a US company building a nearshore team, Panama is a straightforward place to hire.
Panama also has one feature that makes it unusually simple to pay: the country uses the US dollar as its everyday cash. The Panamanian balboa has been pegged to the dollar at 1:1 since 1904, Panama prints no banknotes of its own, and US dollar bills circulate as legal tender. So a US company pays a Panamanian contractor in USD with no currency conversion at all. There is no peso, real, or sol to convert into, and so no FX margin on the conversion itself, which is the single biggest cost in most cross-border contractor payments.
The wrinkle that catches US founders off guard is the treaty position. Panama does not have an income tax treaty with the US, which changes how the W-8BEN analysis reads. The freelancer setup itself is standard, with the independent professional registering a RUC and issuing an electronic factura through the Direccion General de Ingresos. This guide covers what a US company needs to pay Panamanian contractors. We cover the US side (W-8BEN, the no-treaty reality, 1042-S), the Panama side (RUC, the DGI, the factura, ITBMS, the territorial system), and the payment rail decision. This is general information, not tax or legal advice. If you want to skip the assembly and let a platform handle it, Omnivoo Contract Management handles SOW drafting, W-8BEN collection, invoice capture, and payment settlement for a flat $49 per contract.
US side: what you need to do as the payer
Step 1. Collect a W-8BEN before the first payment
Before any invoice is paid, the Panamanian contractor must complete Form W-8BEN and return it to you. The form certifies the contractor is the beneficial owner of the income, is a tax resident of Panama, and is not a US person. The IRS Form W-8BEN page has the current form and instructions.
The W-8BEN is valid for three calendar years after signature and must be refreshed when it expires or when a relevant fact changes, such as address. If your contractor operates through a registered Panamanian company (a sociedad anonima or similar), the form is Form W-8BEN-E, the entity equivalent, available on the IRS W-8BEN-E page. Because there is no treaty (covered below), the treaty-claim section of the form is left blank. The form’s value here is documenting foreign status, not claiming a reduced rate. Our W-8BEN checklist walks through what to verify before the first payment.
Step 2. Confirm the work is performed in Panama
Under IRS source of income rules for personal services, services income is sourced to the place where the services are physically performed, regardless of where the contract was made or the residence of the payer. If your Panamanian contractor does the work entirely from Panama City, Colon, David, or anywhere else in Panama, the income is foreign source income from the US perspective.
For a typical pure services engagement where the Panamanian contractor never sets foot in the US, the result is: no withholding, no Form 1042-S, and no 1099-NEC, which is for US persons only. You keep the W-8BEN, the services agreement, the contractor’s factura, and the payment receipt as the documentation packet.
If the contractor visits the US for an onsite sprint, the days physically worked inside the US are US source days. Those days have to be allocated and may trigger withholding plus a 1042-S, so keep a simple onsite-days log. This matters more here because there is no treaty rate to soften the US source piece.
Step 3. No US-Panama income tax treaty
This is the part that distinguishes Panama from a treaty country like Chile. Panama is not on the IRS list of US income tax treaties A to Z. There is no comprehensive income tax treaty in force between the two countries.
One point of confusion is worth clearing up. The US and Panama do have a tax information exchange agreement, which lets the two tax authorities share information on request. That is an information-sharing arrangement, not an income tax treaty, and it does not create a reduced withholding rate or any treaty article you can cite. So for the purpose of withholding analysis, Panama is treated as a no-treaty country.
What that means in practice is narrow. For US source income, such as days a contractor physically works inside the US or a US-source royalty characterisation, the default US withholding under the statute is 30 percent and there is no treaty rate to reduce it, and no Form 8233 treaty exemption to file. For purely offshore services performed in Panama, the absence of a treaty is a non-issue, because the US has no withholding right in the first place under the source rules. The clean practice is the same as everywhere: draft the SOW as a pure services agreement with full IP assignment, so the fee is not split into a royalty component that could create US source income. For background on how treaties work in general, and why their absence matters here, see our income tax treaty glossary entry.
Panama side: what your contractor handles
You as the US payer are not in scope for most Panamanian taxes. The Panamanian contractor is. Understanding the landscape helps you have an informed conversation about invoice format, ITBMS treatment, and the contractor’s setup.
The RUC, the DGI, and the factura
Most Panamanian freelancers working with international clients operate as an independent professional. They register their activity with the Direccion General de Ingresos (DGI), hold a RUC (Registro Unico de Contribuyentes, the tax number), and issue an electronic factura (invoice) for each engagement.
The factura is the contractor’s invoice. You as the US payer do not need to know the internal mechanics. You only need to receive a valid factura and keep it in your packet alongside the W-8BEN and services agreement.
The territorial tax system
Panama taxes citizens and residents only on income earned from Panamanian sources, which is what a territorial system means, per the PwC summary of Panama personal income tax. The contractor declares and pays their own Panamanian income tax under that system. It is a domestic matter that affects how your contractor reports their earnings, not an obligation that reaches you. Whether and how a given engagement falls inside the Panama-source base depends on the contractor’s circumstances, which their accountant confirms.
ITBMS 7 percent and the export-of-services question
Panama’s value-added tax is the ITBMS (Impuesto de Transferencia de Bienes Muebles y Prestacion de Servicios). The standard rate is 7 percent, with higher rates of 10 percent on alcoholic beverages and hotel accommodation and 15 percent on tobacco and tobacco products, per the PwC summary of Panama other taxes. ITBMS applies to the transfer of movable goods and a broad range of services.
Whether ITBMS appears on your contractor’s factura depends on the contractor’s activity and registration. Exports are not taxed under ITBMS, and combined with Panama’s territorial system a services invoice billed to a US customer commonly sits outside the ITBMS base, but the exact treatment depends on the contractor’s classification. Their accountant confirms whether the factura to a US customer carries ITBMS or is treated as an out-of-scope export of services.
The payment rail decision
This is where Panama is genuinely easier than most countries. Panama uses the US dollar as its everyday cash, so there is no currency to convert into. A US company sends USD and the contractor receives USD.
| Rail | Typical cost | Speed | Notes |
|---|---|---|---|
| US bank SWIFT wire to a Panamanian USD account | Correspondent and intermediary fees, no FX | 2 to 4 business days | No conversion, but fixed bank fees can still apply |
| Transparent USD provider to a USD account or balance | Low, no FX margin on conversion | Same to next business day | Cleanest, since there is no currency to convert |
| US-to-US transfer where the contractor holds a US-accessible USD balance | Lowest | Fast | Where available, removes cross-border friction entirely |
Because the payment never leaves USD, there is no FX margin on a conversion to mark up, which is the cost that dominates payments to most other countries. The remaining cost is the fixed and correspondent fees on the cross-border USD transfer itself. A SWIFT wire works and is a reasonable fallback for one-off larger payments, but a transparent provider that lands USD into the contractor’s USD account avoids most of the intermediary-bank leakage. For a deeper comparison of where money is lost in cross-border payments, see our guide on FX margin in international contractor payments.
Misclassification risk in Panama
Panama, like much of Latin America, distinguishes a genuine independent contractor from a disguised employment relationship, and the principle that the true nature of the relationship governs over the contract label applies. The risk is highest when the contractor has only one client (your US company), works fixed hours under your direction, uses your equipment, and is integrated into your team like an employee. A reclassification can carry retroactive entitlement to benefits, social contributions, and severance.
The mitigations are the same as in other markets: a properly drafted services agreement that establishes the contractor relationship in substance, a scope tied to deliverables not hours, evidence the contractor has other clients, and a documented review of worker misclassification risk at six and twelve months. A clean engagement also lowers the risk of creating a permanent establishment for your US company. For more depth, see our guide on drafting an SOW for global contractors. The Omnivoo Contract Management SOW templates bake these protections in by default, including clear IP assignment and a governing law clause.
End-to-end workflow
Here is the clean version for a US company onboarding its first Panamanian contractor.
- Send the contractor a B2B services agreement that defines deliverables, payment, IP assignment, and termination, anchored by a master service agreement and a statement of work.
- Collect a signed W-8BEN before any payment moves, leaving the treaty section blank since there is no income tax treaty.
- Confirm the contractor is registered with the DGI, holds a RUC, and can issue an electronic factura for each payment.
- Pick a payment rail that moves USD cleanly into the contractor’s USD account, since no currency conversion is involved, and onboard the contractor’s payout details.
- Pay the invoice on schedule in USD. Keep the W-8BEN, services agreement, factura, and payment receipt together as a packet.
- Review the engagement quarterly for misclassification risk and refresh the W-8BEN every three years.
If you are also comparing rails across countries, our global contractor payment methods compared 2026 guide covers the broader options, and our guide on how to pay international contractors from the US walks the general framework. If you pay contractors elsewhere in Latin America, see our guides on paying Colombian, Costa Rican, Ecuadorian, Peruvian, Chilean, and Mexican contractors, plus our regional overview on paying Latin American contractors from the US.
When a platform pays for itself
A US founder paying one Panamanian contractor can do this manually. A US team paying five or more Panamanian contractors faces enough W-8BEN refreshes, factura confirmations, and payment-rail questions that a platform pays for itself within the first few months.
Omnivoo Contract Management costs a flat $49 per contract. We draft the B2B services agreement with Panama-specific IP and misclassification clauses, collect the W-8BEN, capture the factura on every payment, run the USD payment through a clean rail to avoid SWIFT leakage, and store the full packet for audit. Transaction fees are passed through at cost, with no FX markup and no subscription.
A simple sanity check
Three questions for every Panamanian contractor relationship.
- Is there a signed W-8BEN on file (treaty section blank) and is it less than three years old?
- Will all the work be performed in Panama for the foreseeable future?
- Are we paying USD through a rail that lands cleanly into the contractor’s USD account and captures the factura for every payment?
If yes to all three, you are most of the way to a clean US-Panama contractor payment stack, with the bonus that there is no currency conversion to worry about. The remaining work is misclassification hygiene over time.
